My preview crashes whenever I compare my model's value to a constant's stored value. I use struct constants with a stored value as alternatives to enums, (IIRC ever since the beginning) enums never worked at all with .rawValue or computed properties. This crashes when it runs on Xcode 16.3 beta and iOS 18.4 in previews. It doesn't appear to crash in simulator. @Model class Media { @Attribute(.unique) var id: UUID = UUID() @Attribute var type: MediaType init(type: MediaType) { self.type = type } static var predicate: (Predicate<Media>) { let image = MediaType.image.value let predicate = #Predicate<Media> { media in media.type.value == image } return predicate } } struct MediaType: Codable, Equatable, Hashable { static let image: MediaType = .init(value: 0) static let video: MediaType = .init(value: 1) static let audio: MediaType = .init(value: 2) var value: Int } My application crashes with "Application crashed due to fatalError in Schema.swift at line 320." KeyPath \Media.<computed 0x000000034082a33c (MediaType)>.value points to a field (<computed 0x000000034082a33c (MediaType)>) that is unknown to Media and cannot be used. This appears to also occur if I am using a generic/any func and use protocols to access a property which is a simple String, such as id or name, despite it being a stored SwiftData attribute. I filed a bug report, but looking to hear workarounds.

Since iOS 18.2 the simulators have been missing the content under Apps menu for Settings. We are on to iOS 18.3 and still no Apps settings. @dts

Hello! I'm working on implementing SwiftUI + StoreKit2 IAP in my app, and Xcode testing has been fantastic, now I'd like to test my app with Sandbox, where I created a Sandbox account, and it works on my physical device, I can log in, make transactions, etc. (btw, feedback: please improve the UX for Sandbox testing, it's really clumsy compared to Xcode testing with Transaction Manager) My problem is that when I'd like to log in with my Sandbox account on the simulator (Settings -&gt; Developer -&gt; Sandbox Apple Account (at the bottom) -&gt; Sign in), it doesn't work, it fails silently. I know it authenticates well, because if I type in the wrong password, I get an error popup, but with the right password, it just fails silently, hides the login sheet and the "Sign in" text remains "Sign in" (on my phone when I log in, the "Sign in" is replaced with the email address of the Sandbox account). I know many people get errors, and they recommend to go icloud.com and acccept TOS (done that), also to download the latest iOS for the simulator (also done), these are not a problem for me, as I don't get any errors. My authentication works, but for some reason the simulator still won't log in, it fails silently, and I see no errors/reason why. Tried with different simulators (latest iOS version), same result, tried to reboot the simulator, same result. Any idea why is this happening? Thank you, sendai

When I try to build my project in Xcode (from Unity AR) project, it throws me these errors: I feel like I've tried everything to make the LaunchScreen work. I downloaded xcode the night I tried running this build, so the whole deleting and redownloading and restarting everything didn't work. I've tried making sure my macbook and terminal are fully up to date. I literally can't find a solution! Please help!! I will also say, I'm fairly new to App building, Xcode, and Unity. But this does seem like a barrier that is stopping me from testing my project.

I got this error when I upgraded to Xcode 16.2. Unfortunately, my project doesn't run anymore. Can anyone help me? I've been postponing my deadline for a week now '/Users/vdngo/Library/Developer/Xcode/DerivedData/TMC-fiptdrksdfjwrwcdphljlfpuvmmy/Build/Intermediates.noindex/PrecompiledHeaders/TMC-Bridging-Header-swift_1IG9GDIWH1MAW-clang_UTPY7SDIWAR0.pch' for bridging header '/Users/vdngo/.../ios/TMC/Others/TMC-Bridging-Header.h'

I have some formatting strings that got in my string catalog, e.g. "%@" or "(%@)". However these strings are no longer used in my code anywhere (searching "In this project" in Xcode only matches the entries in my strings catalog), but Xcode does not remove them. I tried editing the file in a text editor, removing them manually but they keep coming back. Any solution for this? Xcode Version 15.4 (15F31d)

Hi, I currently have an app that connect to an arduno via CoreBluetooth. However, the app no longer discovers the arduino when the operating system was upgraded to iOS 18.3.1, however on iOS version 17.6.1 the ardiuno was discoverable I was able to test this theory on two different phones each with different iOS versions. Why are my peripherals no longer being discovered with this update? and what is the solution?

ive been using the mac m1 for almmost a year and it used to run vision pro simulator on xcode 15 quite smoothly but now its quitting unexpectedly showing errors in loading the realtiykit content

I just started working with Flutter. I use a Macbook m2 and my phone is an iPhone XR. I made a very simple application but no matter what I did, I couldn't start my application on my iPhone XR. I got help from all the AIs but we couldn't do it. I deleted everything including Xcode, Android Studio and Flutter and reinstalled them and I followed the SDK installation step by step on the Flutter page but I can't run my project on Xcode. I entered my Apple account including all the signings and certificates via the .workspace file extension but it didn't work. The error I get from Xcode keeps changing. We installed podfiles with the support I got from the AIs and after some fiddling, I got the only error right now: Command PhaseScriptExecution failed with a nonzero exit code

Hi, Our team is facing an issue where the os log message is not fully printed in the Xcode console. Even when using Debug → Attach to Process by PID or Name, the logs appear truncated (Both simulator and physical device). We noticed that the Xcode 15.0 release notes we saw that there is some truncation made for debug lines in console. We also tried checking the logs using Console.app, but the truncation remains. If limitation is there how much maximum lines it can print ? Could anyone please provide guidance on how we can view the complete logs? Any suggestions or workarounds would be highly appreciated.

I received the attached crash report. The problem is that the crash report does not contain the abort reason - it appears to be thrown in the GCD library with no additional information. Is it a possible deadlock? 2023-02-15_02-40-23.0077_+0100-94015bd052c4005658221a5e6279f28a75b9e92c.crash Any ideas?

Hi, I currently have an app that connect to an arduno via CoreBluetooth. However, the app no longer discovers the arduino when the operating system was upgraded to iOS 18.3.1, however on iOS version 17.6.1 the ardiuno was discoverable I was able to test this theory on two different phones each with different iOS versions. I see that it is failing to find the peripheral at the scan however the logs indicate that the central state is powered on. Why are my peripherals no longer being discovered with this update? and what is the solution?

I'm using a CMake project and Xcode decided that it would ignore or completely change my file tree to some random one. It has Source files (not a folder in my project) and completely ignores my class folder and header folder. It created it's own Header Files folder. How do I revert this? Why is this even a thing.

I am experiencing a crash when performing a batch delete and merging changes on a Core Data store that uses NSPersistentCloudKitContainer. The crash appears to be triggered when positive fractional Decimal values are stored in a TransactionSplit entity (those values are aggregated via a derived attribute in the AccountTransaction entity). If I store whole numbers or negative fractional decimals, deletion seems to work correctly. I suspect that the issue is related to the internal representation of positive fractional decimals in conjunction with a derived attribute. Data Model Setup: Account (1:N relationship → AccountTransaction) AccountTransaction (1:N relationship → TransactionSplit), which contains a derived attribute (e.g., “splits.amount.@sum”) that computes the sum over the “amount” attribute on its related TransactionSplit objects. TransactionSplit, which contains a stored Decimal attribute named “amount” (of type Decimal/NSDecimalNumber). Steps to Reproduce: Insert sample data where each TransactionSplit’s “amount” is set to a positive fractional value (e.g., 1000.01), by using code similar to: func createSampleData() { // Execute all creation on the context’s queue. let checkingAccount = Account(context: context) checkingAccount.id = UUID() checkingAccount.name = "Main Checking" let randomTransactionCount = 1000 for _ in 0..<randomTransactionCount { let transaction = AccountTransaction(context: context) transaction.id = UUID() transaction.account = checkingAccount let randomValue = Double.random(in: 5...5000) let decimalValue = NSDecimalNumber(value: randomValue) let split1 = TransactionSplit(context: context) split1.id = UUID() split1.amount = decimalValue split1.transaction = transaction let split2 = TransactionSplit(context: context) split2.id = UUID() split2.amount = decimalValue split2.transaction = transaction } save() } The AccountTransaction’s derived attribute automatically aggregates the sum of its related TransactionSplit amounts. Perform a batch deletion using NSBatchDeleteRequest (with resultType set to .resultTypeObjectIDs) on your entities and merge the changes back into your main context: private func delete(_ fetchRequest: NSFetchRequest<NSFetchRequestResult>) { let batchDeleteRequest = NSBatchDeleteRequest(fetchRequest: fetchRequest) batchDeleteRequest.resultType = .resultTypeObjectIDs // ⚠️ When performing a batch delete we need to make sure we read the result back // then merge all the changes from that result back into our live view context // so that the two stay in sync. if let delete = try? context.execute(batchDeleteRequest) as? NSBatchDeleteResult { let changes = [NSDeletedObjectsKey: delete.result as? [NSManagedObjectID] ?? []] NSManagedObjectContext.mergeChanges(fromRemoteContextSave: changes, into: [context]) } } Save the context after deletion.

I'm trying to improve my build time on macOS by not building for x86_64. I've got the following settings: This gets Xcode not to build x86_64 for my app, but not all the package dependencies. I've updated most of the packages to swift-tools-version: 6.0 but FlatBuffers is still on 5.8 and .macOS(.v10_14). GPT claims: If your deployment target is set to macOS 10.15 or earlier, Xcode may force x86_64 support for compatibility reasons. But Xcode is building x86_64 for ALL my packages, even the ones that don't depend on FlatBuffers. When I open a package in Xcode that depends on FlatBuffers, then it builds arm only, so that may be a red herring. Not sure what else to try.

We are trying to create a screentime app using the Family Controls as well as Device activity frameworks. The build succeeds but while pushing to an iphone we are getting an info.plist file for deviceactivity.framework could not be found error. For reference when using the Screentime API a physical device must be used not a simulator. When we remove the device activity framework this error also occurs for the family controls framework. We have added the Family Controls(development) Capability and applied for the distribution capability. We have redownloaded xcode multiple times on the main device, deleted derived data, and redownloaded all of the iphone SDKs and the issue still persists.

I am currently working on creating a virtual interior design app. Can an app made with the Room Plan API be used on iPhones without LIDAR? If so, how much accuracy would be lost compared to iPhones with LIDAR?

xcode15.1 debug does not show the value on the real machine but only the address of the pointer, but on the emulator it shows the normal value. But in the emulator it shows the normal value. xcode15.2 debug doesn't show the value but only the address of the pointer in both the real machine and the emulator. In Xcode14, the value is displayed normally in both the real machine and the emulator. What do I need to do to get it back to the way it was in Xcode14?

Hi everyone, I've been working on an iOS app for about a year and a half. That application comes with unit and UI automated testings. Recently I started the development of the tvOS application so I added a new target and used the same bundle id as I want to eventually share purchases. What I need I'm working on an application that uses VLC (Need to play media more exotic than MP4) through these two pods pod 'MobileVLCKit', '3.6.0' (Only for iOS) pod 'TVVLCKit', '3.6.0' (Only for tvOS) What works Compilation works fine for both targets Unit tests work fine for both targets UI tests work fine ONLY for the original iOS target What doesn't work and how it fails When I launch the UI tests for the tvOS target, the compilation succeeds, but I get an error when calling app.launch() from my XCTestCase. Failed to get launch progress for <XCUIApplicationImpl: 0x600000c61e90 abergia.com.iptv at ...AppPath...>: App installation failed: Unable to Install “...AppName...”. This app is not made for this device. This app was not built to support this device family; app is compatible with ( 1, 2 ) but this device supports ( 3 ). (Underlying Error: Unable to Install “...AppName...”. This app is not made for this device. This app was not built to support this device family; app is compatible with ( 1, 2 ) but this device supports ( 3 ). What I tried Single target - Both Pods It looks like I can 'cheat' a little the system and make the Xcode target compatible with both iOS and tvO, but when declaring both pods inside the same CocoaPod target, the installation fails as one of the library is not compatible. Use a newer version of VLC (4.0.0) Works BUT that version is way too unstable, I will eventually use it again once they fix all the issues. Different Bundle ID Changing the bundle id of the tvOS application resolves the issue BUT I really want to use the same bundle id to share the purchases. Not UI testing the tvOS version It's an option I'm starting to contemplate out of frustration but I'm sure that we have people here who can help me!

Dear Apple Developer Forum! I'm in need of help regarding an issue that has to do with binaries. I'm building an iOS App that needs a fingerprint of its binaries, exclusively based on the source code written. A "reproducible" build, meaning that when I compile it on my machine and run checksum on it, the output (hash) will be the same, as if another device clones the project, compiles and checksums the values. The App depends on swift packages which depends on Swift Packages, which I've managed to compile to .o files, convert to .a files (static frameworks) and create xcframeworks, which the App depends on. They work great, once compiled, their checksum value does not change when App is compiled (unless source code of them is changed of course), but the Apps executable (checksummed inside the IPA) changes every time it's compiled. I'm guessing that perhaps the Xcode compiler injects a timestamp or other unique identifier in the binaries? Is there any way to have "reproducible" builds on iOS (Swift Xcode)? All input is greatly appreciated, Thank you very much, Kind regards Johan.
